HEATING APPARATUS.

Specification of Letters IEatent.

Patented Jan. 6, 1920.

Application filed November 28, 1917. Serial No. 204,313.

To all whom it may concern:

Be it lmown that I, ALBERT R. PRITCHARD, a citizen of the United States,residing in the borough of Manhattan, in the city, county, and State ofNew York, have invented certain new and useful Improvements in HeatinApparatus.

My invention relates to the art of heatmg and has as its principalobject the provision of convenient means whereby the amount of heatradiated in a room may be controlled at will. I

Further objects of the invention will appear to those skilled in the artupon a perusal of the following specification and claims.

In the drawing filed herewith and formmg part of my application forpatent, Figure 1 is an elevational view of a composite radiatorembodying my invention. Fig. 2 is a detail view broken away toillustrate the interior construction of the lower part of the apparatusshown in Fig. 1.

Referring more particularly to the drawing, 1 is an inlet pipe connectedto the hollow base 2 of a composite or compound radiator through aninlet valve 3, said base 2 having a pipe 2 therein which leads the steamsupplied by pipe 1 to pipe or nipple l. Pipe 4 may be provided ifdesired with a second inlet valve 5 and conducts the steam or otherheating fluid from the hollow base 2 to the lower end of the radiatorelement 6. Leading from the upper end of the radiator element 6 is anoutlet pipe 7 provided with a valve 8, the pipe 7 connecting with thehollow top member 9 of a second radiator element arranged to receive itsheating fluid from the first-mentioned radiator element 6. The saidsecond radiator element or unit comprises a plurality of down castmembers such as 10, which lead from the member 9 t0 the base member 2,connection being provided Within the base member 2 between the lowerends of the down cast members 10 and the final outlet pipe 11. Pipe 11has a valve such as 12 therein.

From the foregoing it will be seen that the amount of radiating surfacein use can, according to my apparatus, be efliciently and convenientlycontrolled by closing or opening the valve 8 intermediate the first andsecond elements. It will be understood that when element 6 only is inuse, the apparatus is operated upon the one pipe principle. In thearrangement shown and described, the

apparatus operates upon the two pipe principle when all the heatingsurface is in use. However, it will be evident that the apparatus can bearranged to operate upon the one pipe principle when all the heatingsurface is being employed without departing from the spirit of myinvention.

It will be seen, also, that more than two radiator elements may bearranged accord ing to my invention to receive the heating fluid onefrom the other in series, and that the relative size and disposition ofthe heating elements is immaterial.

Having thus described my invention, I claim:

1. In a heating apparatus in combination, a radiator element, inletconnections at the lower part of said element, a second radiatorelement, a connection intermediate said radiator elements leading fromthe upper part of said first-mentioned element, a valve in saidintermediate connection, a valved inlet to said first element and avalved outlet from said second-mentioned element.

2. In a heating apparatus, a radiator comprising a hollow base member, ahollow top member, radiator members intermediate to said base and topmembers, and a radiator unit intermediate said base and top members,said unit having avalved connection with said top member.

8. In a heating apparatus, a radiator comprising a hollow base member, ahollow top member, radiator members intermediate to said base and topmembers, a radiator unit intermediate said base and top members, andvalved connections between said unit and said base and top members.

4:. In a heating apparatus, a radiator ap' paratus comprising an upcastunit including a plurality of radiating members, a. downcast unitreceiving steam from said upcast unit and including a plurality ofradiating members, a valve whereby the flow between said units may becontrolled, and a valve whereby the inflow of said upcast unit may becontrolled.

5. In a heating apparatus, a radiator apparatus comprising a unit havinghollow top and bottom members, and means, for conducting heating fluidbetween said members, and a second unit comprising a plurality ofradiating members connected as a whole to said top member of said firstunit.

6. In a heating apparatus, a radiator apparatus comprising a unit havinghollow top top and bottom members and means for conducting heating fiuidbetween said members, 10 a second unit suspended as a whole between saidtop and bottom members, and a valved connection between the top of saidsecond unit and said top member of said first unit.

ALBERT R. PRITOHARD.
